Owning that much cash, why they don't just buy the companies that they need?
Pretty much. If you're at war you need that materials to feed the war machine, which includes the metal to build the plane as well as the computers that go in the cockpit (and let's not forget the knowledge to build it all).
Kind of makes sense.
